Product Advantages
Economical solution for low current applications – For control circuits, auxiliary grounding, and signal bonding where current ratings are moderate, this lug‑type connector offers reliable performance at a lower cost compared to heavy-duty compression terminals.
High flexibility & vibration absorption – The stranded fine wires dampen mechanical stress, prevent fatigue failure at rigid connection points, and compensate for thermal expansion, making the connector ideal for dynamic or space-limited installations.
Wide compatibility – Stock sizes (1.5mm² - 500mm²) and common lug types (ring, fork, flag, rectangular) meet most industrial needs, with full customization available for non-standard requirements.
Multiple plating options – Choose from bare, tin, nickel, or silver plating to match your specific temperature range and corrosion environment.
Operating Conditions
Maintenance & Service Life
Maintenance: Periodic visual check for damage/corrosion; clean with dry air or soft brush.
Service life: >20 years under normal conditions. Frequent flexing reduces life.
Replace if: Ferrule cracks, overheating discoloration, or broken braid strands occur.
After-Sales Service
Free technical support: Engineering consultation, drawings, and dimensioning assistance.
Custom orders: Lead time & quality report provided before shipment.

Frequently Asked Questions (FAQ)
Q1: What copper material is used for these flexible wire connectors?
We use premium annealed Cu-ETP wires (C11000) with a certified copper purity ≥ 99.95%, ensuring exceptional electrical conductivity, flexibility, and longevity.
Q2: What surface plating options can I choose from?
We provide bare copper, tin plating, nickel plating, and silver plating to meet diverse temperature ratings, oxidation resistance, and harsh chemical environment needs.
Q3: What is the standard wire diameter, and can it be adjusted?
The default single wire diameter is 0.15 mm. We also manufacture options from 0.05 mm (AWG 44) up to 0.254 mm (AWG 30) based on flexibility and current requirements.
Q4: Are these copper connectors suitable for high-vibration applications?
Yes. The fine stranded braided structure dampens mechanical vibrations, absorbs movement stress, and compensates for thermal expansion, protecting against fatigue breakages.
Q5: Can you customize hole diameter, overall length, and lug shapes?
Yes, we provide full custom fabrication. You can customize cross-sectional area (1.5mm² to 500mm²), length (L), hole diameter (d), and terminal lug styles (ring, fork, flag, rectangular).
Q6: What is the typical service life under continuous operation?
The service life exceeds 20 years under standard operating conditions. Regular visual checks for mechanical damage or severe surface discoloration are recommended.
